A 5-year retrospective study of 14 patients with diaphragmatic injuries revealed 9 blunt and 5 penetrating injuries. In the blunt trauma group, 7 were left and 2 were right side. The penetrating diaphragmatic wound consist of 3 left and 2 right sided. Sex ratio was 11: 3, with male predominanace. Preoperative diagnosis was possible in 9 cases and delayed diagnosis [greater than 24 hours occured in 5 cases.Simple chest X-ray was diagnostic or highly suggestive in 7 cases. 7 cases were diagnosed diaphragmatic injuries by computed tomography, fiuroscopy or by explorative operation. All of the cases had association injury. 11 cases of diaphragmatic ruptures were corrected through thoracotomy and 3 cases needed exploratory laparotomy. One death occured after operation due to associated injuries and respiratory failure. Blunt and penetrating diaphragmatic injuries remain a diagnostic challenge and associated injuries, delayed diagnosis determine the outcome.

Three neonates with congenital diaphragmatic eventration underwent intrathoracic operation had marked improvements in symptoms postoperatively. Two were one day of ages, one was 1 month of age, and they were all female and had other congenital abnormalities of lung hypoplasia, cleft palate, nasal polyps and neonatal hepatitis. The right diaphragm was more affected than left as 2:1. The repair for diaphragmatic eventration was performed successfully by plication of remnant diaphragm, and there were no complications postoperatively.

Twelve cases of traumatic diaphragmatic injuries were treated at the Chosun University Hospital from Feb. 1977 to Inn. 1980. The following results were obtained. l. Sex ratio incidence was 5:1, which male patients were predominant. 2. The age distribution at these cases, were ranged from 16 to 43 years of age, and average age was 27 years. 3. Left sided traumatic diaphragmatic injuries were far more common than right, which approximately incidence of 5:1 diaphragmatic injuries were due to blunt trauma [7 cases-traffic accident, 1 case-fall down], and stab wound [4 cases] in etiology. 4. Surgical repairs were done through only thoracotomy incision in blunt trauma cases, and through each thoracic and abdominal incision same time in 2 cases of stab wound. 5. 2 cases {16.7%] of blunt trauma were died before operation at emergency room, and no man died during or following operation. An overall mortality was 16.7%.

Fourteen cases of diaphragmatic hernias surgically treated at the Dept. of Thoracic ＆ Cardiovascular Surgery in Kosin Medical Center from Jan. 1979 to Feb. 1991, were reviewed in this study. This report includ 9 cases of traumatic diaphragmatic hernia, 5 cases of congenital diaphragmatic hernia. Among the traumatic hernias, 5 cases were blunt trauma and 4 cases were penetrating trauma. Five cases of congenital diaphragmatic hernias were presented, including 2 cases of esophageal hiatal hernia, 2 cases of Bochdalek's hernia and a case of Morgagni's hernia. Operation was performed in all patients. Results of all treated cases were excellent.

This case report included 4 cases of traumatic diaphragmatic hernias, 3 cases of non-traumatic diaphragmatic hernias, and 3 cases of eventration of the diaphragm. Among the traumatic hernias, one case was in immediate phase of traumatic diaphragmatic rupture by traffic accident, 2 cases were in intermediate phase with chronic respiratory or vague gastrointestinal symptoms after traffic accident, and the other was developed after an operation, decortication for a chronic empyema with severe pleural calcifications, damaging the diaphragm. Three cases of nontraumatic diaphragmatic hernia were presented, including 2 cases of probable Bochadlek's hernia (Parents refused operation) and a case of Morgagni's hernia with severe gastrointestinal symptoms. And three cases of eventration of the diaphragm with symptoms were also reported. Results of all treated cases were excellent.

The present paper, deals with the dynamic analysis of a thin-walled tower with varying cross-section and additional masses. It, especially, deals with the effect of the rotary inertia of those masses, which have been neglected up to now. Using Galerkin's method, we can find the spectrum of the eigenfrequencies and, also, the shape functions. Finally, we can solve the equations of the problem of the forced vibrations, by using Carson-Laplace's transformation. Applying this method on a tall mast with 2 concentrated masses, we can examine the effect of the rotary inertia and the diaphragmatic operation of the above masses, on the 3 first eigenfrequencies.

외상성 횡격막 파열은 방사선 검사로 진단하기가 어려운 경우가 빈번하다. 다발성 손상을 동반한 37세 남자 환자에서 횡격막 파열이 의심되었으나, 흉부 CT 검사에서는 횡격막 파열을 확인할 수는 없었고 진단을 위해 흉강경을 이용한 수술을 결정하였다. 횡격막 신경이 횡격막으로 들어가는 부위로부터 8 cm정도의 횡격막 파열이 있었고, 횡격막 마비를 동반하였다. 작업창을 5 cm크기로 추가하여 만든 후, 파열된 횡격막을 연속 봉합하였으며, 동시에 횡격막 주름성형술을 시행하였다. 수술 3개월후 시행한 흉부 방사선 사진에서 만족할 만한 결과를 보였다.

While a diaphragmatic rupture commonly results from trauma to the abdomen and chest, a spontaneous diaphragmatic rupture is very rare. A 68-year-old male presented with chest pain that had originated while doing farm work in a squatting position. Images revealed a 5 cm defect of the left diaphragmatic dome, and the entire stomach was displaced into the thorax. The diaphragmatic defect was round and half had a well-demarcated margin. The remaining fragile tissue was completely excised and was closed primarily. The patient was uneventfully discharged and resumed with a normal diet 10 days after the operation.

From March 1986 to August 1992, 18 patients underwent diaphragmatic plication for the diaphragmatic paralyses complicating various pediatric cardiac procedures. Age at operation ranged from 16 day to 84 months with mean age of 11.8 months. In order of decreasing incidence, the primary cardiac procedures included modified Blalock-Taussig shunt [ 5 ], Arterial switch operation [ 4 ], modified Fontan operation [ 2 ], and others [ 7 ]. The suspicious causes of phrenic nerve injury included overzealous pericardial resection [ 7 ], direct trauma during the procedure [ 6 ], dissection of fibrous adhesion around the phrenic nerve [ 3 ] and unknown etiology [ 2 ]. The involved sides of diaphragm were right in 10, left in 7 and bilateral in one. The diagnosis was suspected by the elevation of hem-idiaphragm on chest x-ray and confirmed by fluoroscopy. The interval between primary operation and plication ranged from the day of operation to 38 postoperative days [mean : 14 days]. The method of plication were "Central pleating technique" described by Schwartz in 16 and other techniques in 2. Five patients expired after plication and the cause of death were not thought to be correlated directly with the plication itself. In the remaining 13 survivors, extubation or cessation of positive ventilation could be done between the periods of the day of plication and 14th postoperative days [mean; 3.8day]. We have made the following conclusions : 1] Phrenic nerve paralyses are relatively common complication after pediatric cardiac procedures and the causes of phrenic nerve injury are mostly preventable; 2] Phrenic nerve palsy is associated with corisiderable morbidity; 3] diaphragmatic plication is safe, reliable and can be applicable in patients who are younger age and require prolonged positive pressure ventilation.ntilation.

Congenital diaphragmatic eventration is a rare disease and generally accepted as an abnormally high position of part or all of the diaphragm, usually associated with a marked decrease in muscle fibers and a membranous appearance of the abnormal area. There were 4 cases of the congenital diaphragmatic eventration at the Dept. of Thoracic Surgery, Seoul National University Hospital, from 1957 to 1977. They were two boys and two girls and ranging from 1 day to 3 years of age. They were all repaired by surgical operation and one was expired postoperatively, another one was dead one year later due to complication. The ratio between right and left was 1:3 and their symptoms were cyanosis, dyspnea and frequent respiratory disease. In physical examination there was noted decreased breathing sound on the affected lung field and bowel sound was audible in some cases. Diagnosis was done by Chest X-ray and plication of the affected diaphragm was usually done in operation. There were noted atelectasis and cystic change of the affected side lung. And the liver, colon, spleen and small intestine were found in the dome of the eventrated diaphragm.
